Thanks for the article. I am new to African American hair care and the timing on this article was perfect! What exactly do you mean by pre-poo? It seems self explanatory but just want to make sure I understand.

I have read and heard a lot about hygral fatigue. I really think it is just the lastest "buzzword." I don't believe fatigue occurs because it is necessary for the cuticles to open to receive moisture then close again to retain the moisture and protect the entire fibrous strand. So it is a necessary function. Just like breathing but we don't suffer from "lung fatigue."

Lol. Love your take on it BUT when you eat too much and get obese what happens to you when you shed all the fat? Unsightly excess skin and stretch marks.

That is how I think of hygral fatigue.

I feel that hair that has enjoyed a hot oil treatment or been plasticized with a leave in conditioner receives water better than extremely dry and brittle hair.

I learnt the whole hygral fatigue thing in The Science of Black Hair and it made sense.

My best
Heather

A pre shampoo treatment or pre poo is either a hot oil treatment before you shampoo or spritzing with water and applying a little conditioner to detangle hair before shampooing.
